This study was carried out to prepare a porcelain samples, which can be used as an electrical insulator.  The raw materials used for the preparation are kaolin Duakhla, Arudhma Sand glass and Potash feldspar with weight percentage (45%, 30%, 25%) respectively.  A chemical treatment was performed on kaolin Duakhla, Arudhma Sand glass to remove all the impurities.  The effect of the washing by HCl acid (chemical treatment) was examined by IR Tech.

     With the aid of transfer matrices method and personal computer a computational research has been carried out on the properties of a rectangular model representing the axial field of an electrostatic quadrupole triplet lens.  The path of charged–particles beam traversing the rectangular fields has been determined by solving the trajectory equation of motion in Cartesian coordinates.  A computer program has been written for this purpose.

            Fractal audio compression is based on the concept of a partitioned iterated function system (PIFS). Fractal audio compression exploits the affine redundancy that is commonly present in audio; this redundancy is related to the similarity of an audio with itself.In other words, fractal audio compression finds similar patterns that exist in different scales and different places in audio, and then eliminates as much redundancy as possible.
